Step-by-step explanation:
hope this helps have a good day or night
Rewrite it in the form a^2 - 2ab + b^2, where a = d and b = 2
d^2 - 2(d)(2) + 2^2
Use the Square of Difference: (a - b)^2 = a^2 - 2ab + b^2
(d - 2)^2
Answer:
11/2 = y
Step-by-step explanation:
You have it all but solved. Now, multiply both sides of the equation by 5/2, the inverse of the coefficient of y.
(5/2)(11/5) = (5/2)(2/5)y
11/2 = y
Answer:
(2, -7/2)
Step-by-step explanation:
According to the midpoint theorem;
M(X, Y) = [(ax1+bx2/a+b), ay1+by2/a+b ]
(x1, y1) and (x2, y2) are the coordinates
a:b is the given ratio
Given the following
Coordinate of the line segment (-8, 5) and (4, -3)
Ratio: 5:3
Get the X coordinate;
X = ax1 + bx2 / a+b
X = 5(-8) + 3(4)/5+3
X = -40+12/8
X = -28/8
X = -7/2
Get the Y coordinate
Y = ay1 + by2 / a+b
Y = 5(5) + 3(-3)/5+3
Y = 25-9/8
Y = 16/8
Y = 2
Hence the required coordinate is (2, -7/2)
